Figure 6From: Designs of the divider and special multiplier optimizing T and CNOT gatesQuantum circuits for (a) the modular adder-subtractor (MAS) and (b) the controlled modular adder (CMA). Due to \({X^{n}} = I\) for the even number n and \({X^{n}} = X\) for the odd number n, the circuit in box 1 consists of \(\lceil {n/2} \rceil + 1\) CONT gates, where \(\lceil . \rceil \) is a round-up symbolBack to article page
